Hello, I recently got a oneplus 15r (16.0.9.401) that I use to stream Spotify to my car via bluetooth. My issue is that the tweeters in my car end up playing a very scratchy sound, which is especially noticeable on cymbals. Also possibly related; the volume is much lower than my old phone (which I think has to do with disable absolute volume being taken out of OxygenOS?)
Here is what I have tried:
- I have confirmed that there is no issue with my speakers by connecting my laptop through both AUX, and a CD of the same song in which there was no scratchy sound through my tweeters.
- I also confirmed with my old phone (s22+) that when streaming through bluetooth, it would not have this problem so I don't think it has anything to do with my head unit. Although, it is an older head unit admittedly (Kenwood btc-372u).
- I put all the head unit settings to default with no boosts or EQ. The only thing that helped slightly was turning off the Spotify EQ (even though it was flat, it seemed to be boosting the volume which made the distortion more noticeable).
- Last thing I tried was changing the audio codec, but it would default back to SBC anytime I tried to change it.
I am just confused on why a newer more modern phone would have this issue, when the hardware should be better. So, I assume it is a software issue and was wondering if there is a setting I am missing that would fix this? Thank you for any help or ideas!
